Prepare grill for cooking over direct heat with medium-hot charcoal (medium heat for gas), or pre-heat a grill pan for cooking on a stove-top.

Stir together oil, cumin, salt and pepper, then rub all over pork chops, transferring chops as coated to a dish. Stir together pineapple, onion, peppers, ginger, lime juice, and about 1/2 teaspoon salt in another bowl.

Lightly oil grill rack and grill pork chops (covered only if using a gas grill), turning over once, until just cooked through, 6 to 9 minutes total. Transfer to a clean platter and let stand 5 minutes.

You can either serve the chops with the salsa as is (not cooked), or if you have cooked your chops indoors, you can toss the salsa into the pan for a quick saute right after you remove the meat. This is what we did, just enough to warm it through, and it was delicious.
